      abstract     = {In order to develop a laser-driven spin-polarized 3He-ion
                      beam source available for nuclear-physics experiments as
                      well as for the investigation of polarized nuclear fusion,
                      several challenges have to be overcome. Apart from the
                      provision of a properly polarized 3He gas-jet target, one of
                      the biggest milestones is the demonstration of the general
                      feasibility of laser-induced ion acceleration out of gas-jet
                      targets. Of particular importance is the knowledge about the
                      main ion-emission angles as well as the achievable
                      ion-energy spectra (dependent on the optimal set of laser
                      and target parameters). We report on the results of such a
                      feasibility study performed at PHELIX, GSI Darmstadt. Both
                      3He- and 4He-gas jets $(n_gas$ ∼ $10^19$ cm−3) were
                      illuminated with high-intensity laser pulses, $I_L$ ~
                      $O(10^19$ W $cm^-2).$ The main ion-emission angles could be
                      identified (±90° with respect to the laser-propagation
                      direction) and the ion-energy spectra for all ion species
                      could be extracted: for the optimal laser and target
                      parameters, the high-energy cut-offs for $He^2+,1+$ ions
                      were 4.65 MeV (with a normalized energy uncertainty of Delta
                      E $E^-1$ = 0.033) and 3.27 MeV (Delta E $E^-1$ = 0.055),
                      respectively.},
